TIRE.

Specification of Letters Patient. 'Paivntcd F01). 2f), 1916.

Application filed 11111812, 1915. Serial No. 33,814. l

To all 'whom t may concern y y Beit known that I, Cuantas SfGiLLi- Lann, a citizen of the United States, residing at Springfield, in the county of Greene and State of .Missou'rh hav(` invented new and useful Improvements in Tires, of which the following is a specification.

. wheels.

The invention relates to atire, and more particularly to the class of Spring tires for vehicle, automobile, inotor-cycle, or the like The primary object of the invention is the provision of a'tire of this character wherein the inner pneumatic tube is entirely dispensed with, thereby-eliminating the possibility of punctures and blow-outs, yet the tire possesses` maximum resiliency to absorb `shocks andjars incident to the travel thereof.

Another object of the invention is the provision of a tire of this character wherein the casing is sustained expanded under the action of springs which are mounted in a novel manner therein to assure the desired yieldability to the tire for the absorption of all shocks and jars to relieve the same from the vehicle while in motion.

A still further object of the invention is the provision of' a ltire` of this character wherein the use of rubber is eliminated,

strength thereto, and thus assuring longevity.

A still further object of the invention is the provision of a tire of this character which is simple in construction, thoroughly reliable and efficient in operation, and inexpensivein manufacture.

Withthese and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fullyfdescribed, illustrated in the accompanying drawings,I and pointed -out in the claims hereunto appended.

'In the drawing: Figure 1 is a fragmentary side elevation of a vehicle wheel showing the tire constructed in accordance with the inventionv applied. .Fig 2 is a vertical longitudinalisectional view thereof.\ Fig. 3

is an enlarged vertical transverse sectional view. Fig. 4 is a plan view of one of the washers forming a seat for the spring. Fig. l view thereof. Fig. '6 is a on the line 6-6 of Fig. 3.

Similar reference characters indicate coi'- responding parts throughout the several views in the drawings. l

Referring to the drawings inv detail, A designates a portion of a. vehilewheel having the usual felly B upon which is mounted the tire hereinafter fully described.

The tire comprises a channeled annulus 10 which is arranged concentrically about the felly B and is connected thereto through the medium of center bolts 11v which are passed through the annulus and also through the felly, while bolted to` the divergent side fianges 12 of the annulus are the edges of ay iexible casing 13, preferably made fromsoft leather, and having riveted or otherwise fixed at the tread portion thereof within the saine an outwardly bowed reinforcing plate 14, the tread klt'rof the casing being materially thickened'with respect to the remaining portion thereof and carries upon the outer `face thereof a` plurality of substan tially diamond-shaped headed rivets 16 forming an anti-skidding surface;l forthe said casing.

Arranged within the casing 13 at intervals throughout the circumference thereof are diagonallyA disposed coiled compression springs 17 which are at right angles and cross each other at the center ofthe casing.

4Each spring 17--hasv one end engaging a bearing washer 18 formed with a seat 19 to receive the same, and this washer is fastened by means of a rivet Q2 secured in the flanges 12 at opposite sides of the annulus, while the opposite end of each spring has its out erinost coils engaged about a boss 23 cna. pivot bearing 21 which is connected through the medium ofa pivot 25 with the web 26 01' a hoop 27 of T-shape in cross section which is fixed to the plate 14, Ithe boss being formed with a central slot 28 vwhichl re ceives the hook end 29 of the spring 17, and this hook end is engaged by a securing pin 30 passed transversely through the boss for the fastening of the end of the spring to the bearing.

Vithin the casing 13 and augmenting the springs 17 are the independemt series of coiled compression springs 31 and 32, respectively, which have their outer ends fixed to the hanger bearings 33 having the bosses 2b in a manner similar to the fixing of the springs 17 to th'e bearings 24, while the inner course understood that the required number lof hoops 27 are fixed to the plate le concentrically about the tire. The springs 31 are of a larger size with respect to the springs 32 so that the resistance thereof is greater than thesprings 32 for absorbing shocks and'jars incident to the travel of the tire. Secured in the hoops 27 are eye members 35, in which are loosely connected coupling links 36 which exibly unite the hoops to prevent the lateral separation thereof when subjected tov shocks and jarsimparted to the tire, lyet the said casing 13-is freely iexible, While the springs absorhthe shocks and jars.

- Mounted at intervals centrally in the annulus 10'are guideeyes 37 while the hoops 27 have pivoted thereto anchor rods 38 which cross each other in pairs and areslidably-engaged inthe eyes 37, the free ends of the anchor rods 38ibeing formed With abutment heads 39 which limit the sliding moveme'n'tof the lsaid rods in the eyes'in one direction, and these anchor rods prevent undue circumferential movement of `the tire or the possibility of the twisting ofthe springs during the pulling action of the Wheel.

Whatl is 'claimed' is 1 A tire of the class described comprising "a channeled annulus adapted to be, se-'.

cured'y to the felly of awheel, a flexible casing connected with the side anges of the annulus and having a thickened tread, a reinforcing plate secured to the inner surface of the casing at the tread thereof, hoops fixed to the reinforcingplate and having hangerl Webs, lWasher vbearings resting against the annulus, hanger bearings pivoted to the said hanger Webs, andcompression members connected `vvith thesaid bearings and engaged Withthe Washer bearings.

2. A tire offthe class described comprising .a channeled annulus adapted to be secured to the felly ofa ivheel, -a flexible casing connected With the side flanges of the annulus capas qt this patent may be pbtaineq f o'r and having a thickened tread,- a reinforcing plate secured to the inner surface of the nected with the side flanges of the annulusV ,and having a thickened tread, a reinforcing plate secured to the inner surface of the casingl at the tread thereof, a plurality of hoops secured to the plate, hanger 'bearings pivoted tothe hoops, and a plurality of coiled com# pression springs supported upon the annulus and engaged 'with the hanger bearings.

4, `A tire of the class described comprising a channeled annulus vadapted to be securedl l tothe felly of a Wheel, a flexible casingwconv nected with the side a'nges ofthe annulus and having a thickened tread..a reinforcing plate secured to the inner surface of the casing at the tread thereof, a plurality of hoops secured to the plate, hanger bearings pivoted l to the hoops, a plurality of coiled compres;- sion springs supported upon the annulus and engaged with the hanger bearings, certain of said springs being arranged in diagonal relation and crossing each other at the center of the casing, and anchor members Working in' opposition to each otherand connected with one of the hoops and to the annulus.
